Roy Levesta Jones Jr. is an American-Russian former professional boxer, boxing commentator, boxing trainer, rapper, and actor who holds dual American and Russian citizenship. He competed in boxing from 1989 to 2018, and held multiple world championships in four weight classes, including titles at middleweight, super middleweight, light heavyweight and heavyweight, and is the only boxer in history to start his professional career at junior middleweight and go on to win a heavyweight title.

During his prime, Jones was known for possessing exceptional hand speed, athleticism, movement and reflexes.
